Qiao Yu immediately seized the opportunity and said, "Thank you, Grandpa, I'll take a look at the paper here today. Oh, you don't know, my advisor doesn't play fair, he's starting to assign me research tasks."
"Oh, what kind of tasks?" the elderly man asked further.
Qiao Yu replied loudly, "I originally wanted to choose the Riemann Conjecture, but my advisor vetoed it. He asked me to first study the random prime number generation model and explore its effectiveness in predicting prime number distribution. Sigh..."
As expected, that one sentence infuriated the old man.
"Nonsense! The Riemann Conjecture? It's not that you're unqualified to try, but how far have you even gotten to dare think about the Riemann Conjecture? Do you think you can tackle it all by yourself? Analytic number theory, algebraic number theory, complex analysis, Fourier analysis, functional analysis, probability and stochastic processes, spectral geometry...
